目的：原发性痛经患者疼痛时针刺十七椎穴，观察其不同留针时间的镇痛效应变化及规律，为临床确定最佳留针时间提供依据。方法将符合纳入标准的90例原发性痛经患者随机分为留针20 min组30例，留针30 min组30例及空白等待组30例。应用视觉模拟评分法(VAS)观察治疗前后随时间变化情况，并比较各组间的差异。结果针刺组针刺镇痛效应从针刺10 min时开始显现，镇痛效应随留针时间的延长而递增(P＜0.05)；留针30 min组疗效明显优于留针20 min组(P＜0.01)。结论针刺十七椎穴对原发性痛经患者的即刻止痛作用，留针30 min优于留针20 min。

Objective To treat the patients with primary dysmenorrhea by puncturing Shiqizhui (EX-B8) and observe the change and regularity of the analgesic effect with different needle-retaining time, for providing evidence for the optimal needle-retaining time. Method Ninety eligible subjects with primary dysmenorrhea were randomized into a 20 min group of 30 cases, a 30 min group of 30 cases, and a blank control group of 30 cases. Visual Analogue Scale (VAS) was used to observe the change before and after intervention with the time, and to compare the intergroup differences. Result The acupuncture groups started to show analgesic effect 10 min after needling, and the effect increased with the needle-retaining time (P<0.05);the therapeutic efficacy of the 30 min group was significantly superior to that of the 20 min group (P<0.01). Conclusion Acupuncture at Shiqizhui can produce a real-time analgesic effect for patients with primary dysmenorrhea, and retaining the needle for 30 min is superior to 20 min.
